Gauging Parameter Calculator

GAUGEPARCAL

Overview

Gauging Parameter Calculator (GPC) is a math calculation and simulation tool that helps the battery designer to obtain matching Compensated End of Discharge Voltage (CEDV) coefficients for the specific battery profile. The tool allows the user to increase the accuracy of the fuel gauge IC over temperature.
